11 daysfeat(plat/st): use FCONF to configure platformYann Gautier
Add required code to support FCONF on STM32MP1 platform. The new FW_CONFIG DT file will be inside the FIP, and loaded by BL2. It will be used to configure the addresses where to load other binaries. BL2 should be agnostic of which BL32 is in the FIP (OP-TEE or SP_min), so optee_utils.c is always compiled, and some OP-TEE flags are removed.

11 daysfeat(plat/st): use FIP to load imagesYann Gautier
BL2 still uses the STM32 header binary format to be loaded from ROM code. BL32 and BL33 and their respective device tree files are now put together in a FIP file. One DTB is created for each BL. To reduce their sizes, 2 new dtsi file are in charge of removing useless nodes for a given BL. This is done because BL2 and BL32 share the same device tree files base. The previous way of booting is still available, the compilation flag STM32MP_USE_STM32IMAGE has to be set to 1 in the make command. Some files are duplicated and their names modified with _stm32_ to avoid too much switches in the code.

12 daysrefactor(plat/st): updates for OP-TEEYann Gautier
Protect BL32 (SP_min) with MMU if OP-TEE is not used. Validate OP-TEE header with optee_header_is_valid(). Use default values in bl2_mem_params_descs[]. They will be overwritten in bl2_plat_handle_post_image_load() if OP-TEE is used.

2021-04-21stm32mp1: enable PIE for BL32Yann Gautier
In order to prepare future support of FIP, BL32 (SP_min) is compiled as Position Independent Executable. Change-Id: I15e7cc433fb03e1833002f4fe2eaecb6ed42eb47 Signed-off-by: Yann Gautier <yann.gautier@foss.st.com>
2019-04-23stm32mp1: add OP-TEE supportYann Gautier
Support booting OP-TEE as BL32 boot stage and secure runtime service. OP-TEE executes in internal RAM and uses a secure DDR area to store the pager pagestore. Memory mapping and TZC are configured accordingly prior OP-TEE boot. OP-TEE image is expected in OP-TEE v2 format where a header file describes the effective boot images. This change post processes header file content to get OP-TEE load addresses and set OP-TEE boot arguments.

2019-02-14stm32mp1: make functions and macros more commonYann Gautier
Mainly remove suffix 1 from prefix stm32mp1 in several macros and functions that can be used in drivers shared by different platforms. Change-Id: I2295c44f5b1edac7e80a93c0e8dfd671b36e88e7 Signed-off-by: Yann Gautier <yann.gautier@st.com> Signed-off-by: Etienne Carriere <etienne.carriere@st.com>
2019-01-04Sanitise includes across codebaseAntonio Nino Diaz
Enforce full include path for includes. Deprecate old paths. The following folders inside include/lib have been left unchanged: - include/lib/cpus/${ARCH} - include/lib/el3_runtime/${ARCH} The reason for this change is that having a global namespace for includes isn't a good idea. It defeats one of the advantages of having folders and it introduces problems that are sometimes subtle (because you may not know the header you are actually including if there are two of them). For example, this patch had to be created because two headers were called the same way: e0ea0928d5b7 ("Fix gpio includes of mt8173 platform to avoid collision."). More recently, this patch has had similar problems: 46f9b2c3a282 ("drivers: add tzc380 support"). This problem was introduced in commit 4ecca33988b9 ("Move include and source files to logical locations"). At that time, there weren't too many headers so it wasn't a real issue. However, time has shown that this creates problems. Platforms that want to preserve the way they include headers may add the removed paths to PLAT_INCLUDES, but this is discouraged.

2018-07-24Introduce STMicroelectronics STM32MP1 platformYann Gautier
STM32MP1 is a microprocessor designed by STMicroelectronics, based on a dual Arm Cortex-A7. It is an Armv7-A platform, using dedicated code from TF-A. STM32MP1 uses BL2 compiled with BL2_AT_EL3.
